• Let’s say a car passes by relatively fast. Each of us makes an enunciation regarding the speed at which it was traveling.
  • I can easily see where you are going with this. It is very likely that each of us will say a different number that it won’t be the actual speed of the car(which is a part of reality). It would be either a lower, either a higher speed then the actual one.
  • The number you enunciate depends on our senses and past experiences.
  • Practically it is just an approximation; an opinion you may say.
  • But that is not an opinion. We should not affirm that that is reality in any case, vehemently sustaining that that is the correct speed.
  • But I would say that that is actually what an opinion is.
  • No, an opinion would be you saying the exact speed in meters/s and another opinion would be me saying the same speed in km/s.
  • That is a bit strict I must say. Each of us says something true about a part of reality but in different ways.
  • That would be truly an educated society.
  • That would be an impossible society, obnoxious even. The exact speed of the car is hardly known, the real one. Not even the speedometer is showing the real speed. Instead of 230 km/h, maybe there are 230,834467 km/h.
  • Then we need to take in consideration the Plank distance, the smallest measurable distance; witch is 1 lp =1.616 229(38) x 10^-35 m.(The number was written on the piece of paper he just took from the pocket.)
  • But also the smallest measurable temporal distance, the smallest time unit 1 tp = 5.391 16(13) x 10^-44 s.(The same, the number was written on the piece of paper he just took from the pocket.)So the exact speed should be expressed in terms of lp and maybe tp, something as lp/tp would be an option. You can not be more exact then that.
  • In the end, an opinion is actually just an approximation of the state of (a part of)reality; and not the actual state. The actual state can be determined with well constructed instrumentation.
  • Not even then in most cases.
